We (Dale Weber, N7PKT and I) have been working on porting Asterisk/app_rpt to the<br>TINY (about 3.5 x 3.5 inches) BeagleBoard (arm-based Linux system), using the native<br>(built-in) audio and GPIO hardware to directly interface to radio systems.<br><br>As of this evening, we have success!!<br><br>The BeagleBoard is capable of talking to 2 radios (either half or full duplex)<br>using the radio's COR and CTCSS decoders (sorry, there isnt enough CPU<br>power to do the DSP processing, like in chan_usbradio). It will also talk to<br>a URI (or 2 or maybe even 3??) using chan_simpleusb. <br><br>I am designing an I/O card, which properly conditions both the analog and digital<br>signals in and out of the BeagleBoard, and will provide general-purpose GPIO pins<br>for whatever the user's needs are. It also may contain a DC-DC converter, so that<br>the system may be powered from a 12 volt (well, like maybe 9-18 volt, actually)<br>DC input, allowing use in an automobile and various configuration of battery/solar/<br>wind-power.<br><br>For those interested, I posted the working chan_beagle.c source in the SVN, and<br>will update it as the project moves along. Currently it only supports 1 fully operational<br>channel, but that's because my test hardware was not intended to do anything other<br>then that.<br><br>We will also post the working kernel sources, plus an entire image of the 4GB<br>flash card, for ease of installation.<br><br>JIM WB6NIL<br><br><br> </body>
